Question

When a 37.00 g silver spoon, initially at room temperature, is placed into 250.0mL of 90.00oC tea, it reaches a temperature of 85.00°C. The spoon will have gained ? J of thermal energy.

I got 5237.5 Joules as (mass)x(specific heat capacity)x(Temperature change)=Heat,
which was apparently incorrect.
Please note that we are NOT given the specific heat capacity of silver in this question.

Answer 1

the tea (water) loses the energy gained by the spoon

250.0 * (90.00 - 85.00) * 4.184
